Black Holes in Astrophysics
This article reviews the current status of black hole astrophysics, focusing on topics of interest to a physics audience. Astronomers have discovered dozens of compact objects with masses greater than 3M⊙, the likely maximum mass of a neutron star. These objects are identified as black hole candidates. Some of the candidates have masses ∼ 5− 20M⊙ and are found in X-ray binaries, while the rest ...
متن کاملBraneworld Black Holes in Cosmology and Astrophysics
The braneworld description of our universe entails a large extra dimension and a fundamental scale of gravity that might be lower by several orders of magnitude compared to the Planck scale. An interesting consequence of the braneworld scenario is in the nature of spherically symmetric vacuum solutions to the brane gravitational field equations which could represent black holes with properties ...
متن کاملDirty Black Holes and Hairy Black Holes.
An approach based on considerations of the non-classical energy momentum tensor outside the event horizon of a black hole provides additional physical insight into the nature of discrete quantum hair on black holes and its effect on black hole temperature. Our analysis both extends previous work based on the Euclidean action techniques, and corrects an omission in that work. We also raise sever...
متن کاملGravitational lensing by spinning black holes in astrophysics, and in the movie Interstellar
Interstellar is the first Hollywood movie to attempt depicting a black hole as it would actually be seen by somebody nearby. For this, our team at Double Negative Visual Effects, in collaboration with physicist Kip Thorne, developed a code called Double Negative Gravitational Renderer (DNGR) to solve the equations for ray-bundle (light-beam) propagation through the curved spacetime of a spinnin...
متن کاملBlack - Hole Astrophysics ?
Black-hole astrophysics is not just the investigation of yet another, even if extremely remarkable type of celestial body, but a test of the correctness of our understanding of the very properties of space and time in very strong gravitational fields. Physicists’ excitement at this new prospect for testing theories of fundamental processes is matched by that of astronomers at the possibility to...
